Application filed July 9, 1917.

To all ur/m/lt it may roizcern:

l lo it known that l, VVAL'rl-n: l3. lninin'r'r, a citizen of thelhiited t tates, residing at .wlason ity, in the county of lerro Gordoand h tale of lowa, have invented certain new and useful lniprovenientsin Vehicle Axles: and l do hereby declare the following to be a full.clear, and exact description of tie invention. sucl as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to the front or steering axles of tractors ormotor cars; and it consists in the novel construction and munbination ofthe parts hereinafter fully described and claimed.

ln the drawings, l igure 1 is a front view of a steering axleconstructed according to this invention. Fig. 2 is a plan "view of theaxle. Fig. an end view of the axle. Fig. *l is a crossecction throughthe axle, taken on the line a:-a2 in Fig. 2.

The main frame 2 of the vehicle or tractor is of any ap 'n'ovedconstruction. Two similar angle-shaped brackets 3 are provided, and aresecured parallel to each other and crosswise of the front end portion ofthe frame 2. The upper ends -'1 of these brackets are turned so thatthey lie flat against the sides of the frame, and they are secured to itby liYets 5. The apices of the brackets project donuiwardly of theframe, and 6 is a block provided with laterally projecting trunnions Twhich are pivoted in the lower end portions of the brackets 3 on thelongitudinal axis of the tractor.

.J tn axle frame is provided, and it comprises parallel. upper and lowerbars 8 and 9, suitably connected together by two vertical distancepieces 10 arranged at a, little distance apart and one on each side ofthe center of the block 6, and a brace or braces 12 secured diagonallybetween the middle and the end portions of the bars 8 and 9.

A vertical pin 1 1 is secured to the bars 8 and 9 in the space betweenthe two distance pieces 10. and the block 6 is slidable vertically onthe pin 1-1. A helical spring 15 is arranged to encircle the pin 14 inthe space between the two distance pieces. and between the block 6 andthe lower bar 9 of the axle frame. The weight of the front end portion,of the main frame "3, and the Specification of Letters Patent.

parts carried by it, rests on this spring 1:") which prevents the joltsdue to the roughness of the road from being transmitted to an injuriousextent to the main franie.

Bearing blocks 16 are pivoted. by vertical pins 17 between the upper andlower bars 8 and 9, at the end portions of the axle frame. The bearings18 of these'bloclcs are arranged to one side of, and pcrferably in frontof, the pins 17. Axle spindles 20 are provided and are carried by thebearings '18, and front road wheels 21 of any approved construction arejournaled on the spindles 20. The bearing blocks have forwardlyprojecting arms 22, and 9A: is a com pling-rod pivoted between the freeend portions of the arms 22. One of the axle spindles has a crankedextension 25, and 26 is a portion of the steering-rod which is pivotedto the extension 25. The rod 26 is operated. by any approved means, andit operates the two steering road wheels simultaneously. Suitable braces27 are also provided, and are connected to a crossbar 28 on the mainframe and to the axle fame, so as to permit the main frame to movevertically under the control. of the spring 15, and so as to hold theaxle frame crosswise of the main frame.

These braces 27 are arranged and secured in any approved way, and theyare prefer ably diverging spring braces, and are inclined down\vardl andforwardly, and have their front ends secured to the lower bar 9 of theaxle frame.

A steering axle constructed in this manner inexpensive to manufacture,and it is relatively light and strong, and is not liable to get out oforder.

What I claim is:

1. The combination, with a main frame, and a pair of brackets securedcrosswise thereof and projecting downwardly; of a block provided withtrunnions which are pivoted in the said brackets, an axle f'amecomprising upper and lower bars suitably braced together, means forholding the axle frame crosswise of the main frame, a pin secured to themiddle parts of the said bars and slidable vertically in a hole in thesaid block, a helical spring arranged between the said block and thelower bar of the axle frame, and axle spindles for the road wheelsconnected t the end portions of the axle frame,

2. The combination, with a main frame,

and a pair of brackets secured crosswise thereof and projectingdcmnwzu'dly; of a block provided with trunnione which are pivoted in thesaid brackets, an axle i'rnme comprising upper and lo er hare snitnhlvbraced together, means for holding the t'rnnie crosswise of the mainframe, u pin secured to the middle parts of the said hers and slideblevertically in a hole in the said block, a helical spring arrangedbetween the said block and the lower hair of the axle irunie, bearingblocks pivoted by vertical pins between the end portions oi? the bars ofthe axle frame and provided with been ings arranged to one side of theirpivot pins and axle spindles for the road wheels projecting from thesaid hearings.

In testimony whereof I have e'liiX-ed my signature.
